Lee Donghae had returned to the hospital following his cardiac arrest. Unfortunately, this arrangement is appearing to be long-term as they discovered another abnormality.

His childhood friend, Lee Hyukjae is his roommate again.

Lee Hyuk Jae secretly likes Lee Donghae.

The problem is that Lee Donghae is straight.

You know that stereotypical creepy house that no one goes near? That house that screams “enter at own risk”? Well, what happens when 14 strangers ignore the warning and enter the house, and get sucked into a game they never expected?

A look into the lives of Siwon and Donghae during the happenings of Audio Visual.

S.E.X. stands for Choi Siwon, Korean Tycoon. Charming and witty, he is able to get anyone he wishes without much of an effort. After all, he had both money and looks. He's notorious for having 'pets' -- doting on pretty women and some of the best-looking men to ever capture his fancy. He showered them with gifts and they hung on his arm. At least until he got bored and went hunting for a new one.

It had been months since he'd had a 'pet' and he was beginning to grow restless.

What happens when he sets his sights on an unsuspecting Lee Jun Ki?

It was the strangest sensation he had ever experienced.

Strange how every part of their bodies seemed like latches and locks made to click into place together.

Like together they existed as one whole person.

Two writers are about to realize that what started as a petty rivalry to dominate over each other has turned into something else entirely as they find inspiration in one another and ruin everything that they've fought so hard to get.

After all...isn't love the best climax to fight for?
